whats needed to go blow-throught sq-trim

stanggt00 · Oct 24, 2008

ok guys almost got the motor back in the car my question is what all do i need to covert from draw-throught to a blow-throught set-up

i have the mph mongoose kit (sq-trim vortech,42lb injector)

i ups just dropped off the cobra fuel tank w/pumps off today

whats the max hp i can get out of the stock cobra fuel tank and pumps before i need to upgrade to bap or gt pumps..

and if possible does some one have pictures of there car with blow-throught set-up i will need to know how to run the hoses thxs

Just get yourself a blow thru maf. You will need to relocate where your IAC takes the air in from (in your inlet pipe now). Put it in your pressure pipe AFTER the MAF. Get it retuned and you're done.

ok cool thats was i was thinking just wanted to hear it from one of you guys to be sure

i am also looking at a wastegate and the smallest pulley i can get for the sq-trim

wastegate will be set to say 15psi and anything over that will be purged from the wastegate this should help to give the blower a little more kick on the low side of the rpm band here is what it should look like

1. air enters intake
2.vortech compresses air
3.at the wastegate (if psi < N then wastegate opens) N=wastegate setting
4.intercooler reduces intake charge by (X%)
5.at bov (if intake manifold psi > intake psi then open)
6.pmas reads air charge and temp

also if anyone can fill me in on were the hoses are connected when going from suck to blow througth

i know on suck througth when the maf is at the beginning the hoses connect before the blower

Andy, has that helped in the programming?

Turbo92PGT · Oct 27, 2008

Ya it seems better. my tune isn't dead on just yet, bucks when I let off the gas, but it definitely helped my idle. If I floored it on the freeway and then put it in nuetral after i was done and coasted alot of times my car would die. Haven't had this problem yet with the new setup.

rconaway · Oct 27, 2008

That's interesting as that is similiar to the problem I had. I bought my car as a Steeda and the programming was spot on. As I modded it, we were able to always get a pretty good programming. A couple years ago I started having the problem that as I came off a partial throttle for a period of time, like 5 miles on the freeway, the car would die. No amount of programming fixed that. However, I may have had other engine issues as I was blowing heater cores for example. When we tore the engine down, we had a piston that had warped in the middle and another with damaged rings. I hadn't tried your idea as I just read about it in a magazine a few days ago and then saw this post. We are programming the car now but with the new heads and cam, things are kind of psycho from a horsepower standpoint. The car went from 400rwhp at 6000 rpm's to 500hp at 5000rpms with the Livernois heads and cam. Since it's built to go to 7500rpm, we are just now looking at what we can get away with on 91 octane. However, if I have that stalling problem again, I think I will try moving the MAF.

I would change that setup...when you floor it your supercharger is pushing boost into the valve cover where your crankcase ventilation is. I don't think you should do that, it will pressurize the oil pan. Move those hoses to the suction side of the blower where its vacuum.

looks good just don't put the bov next to the maf, it will create turbulence when it opens and closes, that will affect your drivability

i have a blow thru maf on my car.
first off, put the BOV on the inlet side of the IC. mine was originally on the outlet side (16" down from the MAF) and it caused terrible idle issues. do NOT connect the PCV to the pressurized side of the piping. mine has breathers in it now.

you will peg your MAF faster with a blow thru meter. my SCT3000 is seeing 1015 counts.

honestly if you want the blow thru for the BOV sound, dont do it. it gets REALLY annoying having a BOV that is constantly going off!!!

I don't know man that sound is awesome if you ask me. I've ridden in many of turbo cars and never get tired of hearing the BOV. I guess its another one of those personal preference things.BTW to saleen's bada$$ ride

SaleenGT2001 · Oct 31, 2008

it does sound great on turbo cars. they aren't venting at idle!! trust me.....it is cool for about a month but when you have to hear it blowing off while you are cruising the interstate it gets old fast!!

when i was at MW i would be cruising the strip and it was blowing the sand on the street around like a lead blower!!

why would you wanna convert , draw thru has always been proven to easier tune , and provides better driveability

SaleenGT2001 · Nov 3, 2008

driveability isnt an issue at all with mine. runs as good or better as a stock car once it is warmed up and the cams arent acting up

hey guys it kinda off topic but where is the best and cheapest place to get a cobra tank and pump, i have a procharger and im maxing out the focus pump on the high end

thanks
